I hope it was clear that my "bottom line" was sarcastic. I find myself wondering how the Europeans managed to develop a working, installed ATC system in Ada while the FAA system just drags along. The European airports seem progressively to be adopting versions of the Thomson system. Taken as a whole, European air traffic is not signficantly less voluminous than American traffic - Paris, London, Amsterdam, and Frankfurt are _very_ busy places, and they'd all fit into the American East. A recent posting expressed concern that the FAA system will never be completed. What's holding it up? Maybe we should just adopt the European system (if it were politically possible, which I'm sure it's not). Can anybody enlighten us here? Where are we going wrong? Mike PS - speaking of transportation, I caught a snippet last week at WAdaS that the French high-speed rail network (otherwise known as TGV) is using a bunch of Ada these days. Can anyone confirm or refute?
